Both the forebay and main pond areas of Wet Pond A are already significantly oversized for the drainage area; the additional 0.9% volume in the forebay is not taking any true needed volume away from the main pond or creating a short arching issue.

This permit shall be effective from the date of issuance until September 10, 2028 and shall be subject to the following specified conditions and limitations: t. DESIGN STANDARDS 1. This permit is effective only with respect to the management and volume of stormwater described in the approved pl and specifications. The maximum amount of built -upon area (BUA) allowed for the entire project is 340,287 square feet. 2. The redevelopment portion of this project is exempt from State Stormwater permitting requirements under the following conditions: 1) The project must be constructed as shown on the plans submitted to this Office; 2) the proposed redeveloped BUA of 29,302 square feet does not exceed the existing BUA of 88,759 square feet; and 3) The proposed stormwater control (vegetated sheet flow, vegetated swales, and a piped collection system) provides equal protection of surface waters as the existing stormwater control (vegetated sheet flow and a piped collection system). The low density area must not exceed 24% per the requirements of the stormwater rules. Within this low density area this permit covers the construction of a total of 12,266 square feet of proposed BUA. This permit does not provide any allocation of built -upon area for future development within this low density area. Page 1 of 5 State Stormwater Management Permit No. SW8 080740 4. The low density area has maximized dispersed flow of stormwater runoff through vegetated areas and minimized the channelization of flow. Stormwater runoff that could not be released as dispersed flow may be transported by vegetated conveyances with minimum side slopes of 11 (H:V) designed to not erode during the peak flow from the 10-year storm event as defined in the stormwater rules and approved by the Division. Within the low density area, no piping shall be allowed except those minimum amounts necessary to direct stormwater runoff beneath a BUA such as a road or driveway when it cannot be avoided. 6, The drainage areas for the on -site stormwater systems will be limited to the amounts of built - upon area indicated in this permit and the approved plans and specifications. The runoff from all built -upon area within the permitted drainage areas of this project must be directed into the permitted stormwater control measures. The stormwater control measures labeled Wetland 1, Sand Filter 1, Pond A, Pond B, and Pond C have been designed using the runoff treatment method to handle the runoff from 124,078, 33.809, 55,642, 51,560, and 32,508 square feet of built -upon area, respectively. The built -upon area for future development within these drainage areas is limited to 61,622, 4,000, 1,500, 14,000, and 4,750 square feet, respectively. 7. Where a project or lot is located within CAMA's Area of Environmental Concern (AEC), the Division of Coastal Management (DCM) may calculate a different maximum built -upon area based on CAMA regulations. The more restrictive BUA limit of DCM or DEMLR will apply to the project. 8. A 50-foot wide vegetative setback must be provided and maintained adjacent to all surface waters, measured horizontally from the normal pool elevation of impounded structures, from the top of bank of each side of streams or rivers, and from the mean high waterline of tidal waters, perpendicular to the shoreline in accordance with the stormwater rules and the approved plans and specifications. Within the low density area, all stormwater runoff, including roof drains, shall be released as dispersed flow no closer than at the edge of the vegetated setback and shall not be piped into or through the setback. 9. The stormwater control measures are permitted based on the design criteria presented in the supplements and as shown in the approved plans and specifications. These stormwater control measures must be provided and maintained at the design condition. The approved supplements are incorporated by reference into this permit. 10. Within the constructed wetland drainage area, which is subject to Session Law 2008-211, all runoff being directed into wetlands shall flow into and through those wetlands at a non -erosive velocity. 11. Within the areas subject to the 2017 rules, the peak flow from the 10-year storm event shall not cause erosion downslope of the stormwater outlet discharge point. 12. Decorative spray fountains will be allowed in the wet ponds if documentation is provided demonstrating that the proposed fountain will not cause resuspension of sediment within the pond or cause erosion of the pond side slopes. 13. When using a wet pond for irrigation, it is recommended that some water be maintained in the permanent pool, the vegetated shelf is planted with appropriate species that can handle fluctuating conditions, and human health issues are addressed. 14. The SCM landscape planting plan shown in the approved plans shall be followed in its entirety during construction. After the plants are established, the operation and maintenance agreement must be followed. 15. The sand filter shall be maintained in a manner that results in a drawdown of at least two inches per hour at that sand surface. Page 2 of 5 State Stormwater Management Permit No. SW8 080740 16. The level spreaders and vegetated filter strips shown on the plans are not required by the Division and have not been demonstrated to meet the State Stormwater BMP design requirements and therefore are not considered a part of the approved state stormwater treatment system. These additional measures are incorporated only by reference and are not enforceable parts of the permit. II. SCHEDULE OF COMPLIANCE The project and SCM(s) shall be constructed, operated and maintained in accordance with the conditions of this permit and the approved plans and specifications. Z The on -site stormwater system shall be entirely constructed, vegetated, and operational prior to the construction of any development within the drainage area, per the approved plans and specifications. 3. During construction, erosion shall be kept to a minimum and any eroded areas of the on -site stormwater system will be repaired immediately. If the stormwater system is used as an Erosion Control device, it must be restored to design condition prior to operation as a stormwater treatment device, and prior to occupancy of the facility. 4. All stormwater control measures, stormwater collection systems vegetated conveyance systems, and/or maintenance accesses must be located in public rights -of -way, dedicated common areas that extend to the nearest public right-of-way, and/or permanent recorded easements that extend to the nearest public right-of-way for the purpose of inspection, operation, maintenance, and repair. 5. The permittee shall provide and perform the operation and maintenance necessary, as listed in the signed Operation and Maintenance Agreement to assure that all components of the permitted on -site stormwater system functions at the approved design condition. The approved Operation and Maintenance Agreement is incorporated by reference into this permit and must be followed in its entirety and maintenance must occur at the scheduled intervals. 6. The operation and maintenance agreement must be recorded with the Office of the Register of Deeds. Records of maintenance activities must be kept and made available upon request to authorized personnel of the Division. The records will indicate the date, activity, name of person performing the work and what actions were taken. B. The final plats for the project must be recorded with the Office of the Register of Deeds. The recorded plat must reference the Operation and Maintenance Agreement and must also show all public rights -of -way, dedicated common areas, and/or permanent drainage easements, in accordance with the approved plans. 9. The permittee is responsible for verifying that the proposed built -upon area for the entire project does not exceed the maximum allowed by this permit. 10, Upon completion of the project, the permittee shall determine whether or not the project is in compliance with the permitted plans and take the necessary following actions: a. If the permittee determines that the project is in compliance with the permitted plans, then within 45 days of completion, the permittee shall submit to the Division one hard copy and one electronic copy of the following: i. The completed and signed Designer's Certification provided in Attachment A noting any deviations from the approved plans and specifications. Deviations may require approval from the Division; ii. A copy of the recorded maintenance agreement; iii. Unless already provided, a copy of the recorded deed restrictions and protective covenants; and iv. A copy of the recorded plat delineating the public rights -of -way, dedicated common areas and/or permanent recorded easements, when applicable. b. If the permittee determines that the project is not in compliance with the permitted plans, the permittee shall submit an application to modify the permit within 30 days of completion of the project or provide a plan of action, with a timeline, to bring the site into compliance. Page 3 of 5 State Stormwater Management Permit No. SW8 080740 11, No person or entity, including the permittee, shall alter any component shown in the approved plans and specifications.
